IMPROVEMENT IN STEAM COOKING APPARATUS.

Specification forming part of Letters Patent No. 127,253, dated May 28,1872.

To 'whom it may concern:

Be it known that I, J AMES A. LITTLE, of Cartersburg, in the county ofHendricks and State of Indiana, have invented a new and valuableImprovementin Steam Cooking-llIachines; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawingmaking a part of this specification, and to the letters and iigures ofreference marked thereon.

Figure l of the drawing is a representation of a vertical longitudinalsection of my invention. Fig. 2 is a front elevation of the same. Fig. 3is a rear elevation of the same. Fig. 5 is a detail. Fig. 6 is avertical section.

This invention has relation to an improved steam apparatus in which arecombined afurnace, steamgenerator, fruit-kiln or dryingoven, and a tankto receive cattle feed while the same is being heated and steamed. Thenovelty consists in the construction and arrangement of the partsessential to the abovementioned combination,substantially as hereinafterdescribed.

Referring to the drawing, A represents a steam-chest, supported uponlegs B, and, for convenience, divided into two steam-compartments by acentral partition, b. C represents a furnace, located underneath thesteam-chest. c c are elbow-tubes, leading into the steamchest andcapable of being turned so as to admit of use either as inlet or outlettubes through which the steam-chest may beiilled or emptied. Thesteam-chest is covered by two doors, d d, which are hinged to the backpart thereof. Through the centers of the doors d d openings are made,and to them fitted vertical steamtubes d1 d1. Latches d2 are used tokeep said doors closed. When open and thrown back the doors d d rest ina horizontal position upon a bar, d3, attached to the rear supports ofthe steam-chest.

It will be noticed that the sides a of the chest project beyond thefront and rea-r of said chest 5 the supports B being placed against theends of the side pieces a. By this means la broad foundation is providedrendering the apparatus rmer in its position and not liable to toppleover.

The ends of the pieces a are tenoned or cut down to produce shoulders nlc2 flush with the tops of the supports B. Upon the shoulders a2,adjacent to the bar d3, and upon the rear supports B, the doors d restwhen thrown back, as well as upon the bar d3.

' The chest A may be used for other purposes besides the generation ofsteam; as, for instance, to merely heat water. Thus, the doors d may,when thrown back, be used as a table upon whichl to prepare meats,poultry, vegetables, and the like, the chest being used to scald themin.

D designates frames, the same in size and shape as the doors d,uponwhich they are placed. The tubes d1 pass through openings in the centersof the frames D. These frames are fastened by means of hooks E, whichare attached to loops on the sides and ends of the steam-chest. Theseframes are designed for the purpose of providing a means for renderingthe steam-chest steam-tight. When the frames are fastened in placecommon wedges, e, are driven between the adjacent surfaces ot the doorsd and frames, and by this means the doors are made perfectlysteam-tight.

A soft packing of India rubber or its equivalent may be attached to theedges of the chest A so as to allow the crevice to be more easilyclosed.

F represents a tank or cask, having an aperture in the bottom. This caskis used for holdingcattle feed while the same is bein gsteamed hence, itrests upon one of the frames D when being used. The steam-tube passesthrough the bottom of the cask and has placed over it a perforated tube,e, through which the steam escapes and impregnates the contents of thecask. e represents a cap for the tube e. G indicates a capacious oven,which is designed to rest when in use upon the frames I). This oven isconstructed with an interior metallic casing, H, surrounded by asteam-space, I to which the tubes d] leads; openings m being made in thebottom of the oven for their insertion.

The oven is heated by the steam circulating through the space I. Thisoven may be used for the purpose of drying fruit, clothes, or otherarticles, and for convenience in arranging shelves or clothes-polesracks J are provided. These racks are removable. The oven is furnishedwith doors K, and with a flue, L, to let the moisture pass on". A pipe,M, extends PATENT OFFICE. y

from Athe back of the oven and is provided with a safety-valve, N, tocontrol the pressure of steam. o

It will be observed that the tubes d1 are perforated a short distancebelow their upper ends. These perforationsn1arked n, are designed tobeon a line with the lower surface of the steam-chamber so as to allow thecondensed steam to pass from the space to the steamchest.

The oven is secured in position by means of hooks on connecting withloops attached to the stcam-chest..

The object in view in dividing the steamchest into two or more separatecompartments is to allow of the parts of the chest being used fordifferent purposes. Thus, steam may be generated in one compartmentwhile the other is being used to mix feed in.

What I claim as my invention, and desire to secure by Letters Patent,is-

vl. The furnace C, steam-chest A, doors d,

frames D, steam-tubes di, oven G with lining H and steam-space I, allcombined substantially as and for the purpose specied.

2. The frames D provided with the hooks E secured thereby to thesteam-chest A, arranged upon the chest-lids d, and adapted to receivetightening-wedges z between their under surfaces and ther lids d,substantially as and for the purpose specified.

3. The steam cooking apparatus hereindescribed having the steam-chest Awith hinged lids d holding the tubes d1 and provided with the cask Fhaving the perforated tube e, all constructed and arranged substantiallyas speced.

In testimony that I claim the above I have hereunto subscribed my namein the prese-nce of two witnesses.
